COIN -CONTROL MECHANISM FOR VENDING-MACHIN ES.

Specification of Letters Patent.

Patented May 28, 1918.

Application filed December 1, 1911, Serial No. 663,338. Renewed January 29, 1914. Serial No. 815,290.

To all whom it may concern:

Be it known that I, GARABED G. HEGELN- IAN, a citizen of theUnited States, and a resident of borough of Brooklyn, city of New. York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Coin-Control Mechanism for Vending-Machines, of which the following is a specification.

This invention relates to new and useful improvements in vending machines and the object of my invention is to provide a new and improved vending machine which is simple in construction, strong, durable,-com

pact, quick and reliable in action and not expensive.

In the accompanying drawings in which like numerals of reference indicate like parts in all the figures:

Figure l is a vertical sectional view of my improved vending machine, parts being shown in elevation, and others being broken away.

Fig. 2 is a plan view, parts being broken away and others shown in section.

Fig. 3 is a vertical transverse sect onal view of the machine, on the line aa-w Fig. 2.

Fig. 4 is a pers )ective view of the same.

The entire mec ianism is contained in a comparatively fiat rectangular casing 1 preferably made of sheet iron, one face of which is closed by a removable door 2 provided with a suitable lock 3 of any conven: tional construction. I

A horizontal shaft 4 extends transversely through the casing centrally about one third from the top of the same and is provided on the outer exposed face of the casing with a handle knob 5 for turning it. \Vithin the casing adisk 6 is rigidly mounted on this casing and is provided with an are shaped notch or recess 7 in its run for receiving part of a coin 8, for example, one cent. At each side of the casing l a vertical chute or hopper 9 for the materials to be delivered is arranged which material, for example, may be cakes of chocolate, or candy, etc., suitably wrapped and preferably rectangular in shapeso as to feed freely but without undue play in the hoppers, so that the said cakes of chocolate or other candy can slide down vertically in said hopper. The hopper is preferably bent up of sheet metal as shown in Fig. l and is provided with a slot 10 in the face behind the door. Between the hoppers the coin recep- Each hopper is provided at the bottom and I the outer side with an opening or slot which communicates with a slot or opening 13 in the bottom of the side wall of the casing 1. Behind each hopper, that is between the rear wall of the hopper and the rear Wall of the casing a lever 14 is pivoted at 14 so that it can swing in front of the rear wall of the casing 1, in the direction toward and from the side walls of the casing and each such lever is provided at its lower end with a horizontal arm 15 projecting toward the front of the' casing, said arms being normally located in the recess 12 beneath the hoppers. At its upper end, and at the outer edge, each lever 14 is provided with an angular toe 16 which can enter a corresponding noteh 17 in the inner edge of a locking lever 18, pivoted at 19 so as to swing in front of the rear wall of the casing, and in the. same plane. as the lever 14. The lower end of each locking lever is connected with the upper end of a helical spring 20, the lower end of which at 21 is suitably secured to the rear wall of the hopper or the rear wall of the casing so that this spring will act on the locking lever to swing the same downward and in the direction toward the vertical central planeof the casing, that is the plane through the shaft 4. Each lever 14, above the pivot 141, has its inner edge shaped as a cam surface as at 23-24, with a slight ofi'set or beveled shoulder 25 between these cam edges. Coin chutes 26, terminating-in slots at 27 in the top of the casing, lead to the disk 6. The levers 14 are normally in the position shown at the ri ht hand side of Fig. 1 and the several cities of candy or other articles in the corresponding chute rest one upon the other, the lowest one resting upon the arm 15 of the corresponding lever 14. For example, if the coin is inserted in the left hand coin chute, Fig. 1. this coin 8 will pass into the notch 7 as far as possible, when the notch is at the top, and if the notch is not at the topat the time the coin will rest on the edge of the disk 6 until the same has been turned in either direction to such an extent that the coin drops into said notch and will now Lilo participate in the turning movement of the dish 6 in the direction from right to left, The coin cannot escape from the notch Z and acts on the bevel side '28 of the lefi, hand locking lever 18, forces this locking lever against the tension of the spring 20 toward the left hand side of the casing and the coin is carried down to the cam surface 23 at the upper end of the left hand lever ll and forces the upper end of this corre sponding lever l-l some distance to the left thereby swinging the corresponding arm 15 on the lower end of said left hand lever 1% partially from under the lowermost candy or other article in the left hand chute or hopper but not entirely from under the same. This is possible because the locking lever has been moved so far to the left as to permit the angular toe 16 on the upper end of the lever i lto leave the notch 17 in the locking lever but at the same tirne the spring 20 has brought the curved edge 29 of the locking lever over the coin, thus preventing turning the shaft in the reverse direction, that, is, from left to right, with a view oi extracting the coin which shifted the parts to the extent shown. By continued turning of the disk 6 by means of the handle knob 5 in the direction of right to left, Fig, l, the coin swings the upper end of the lever ll and the spring actuated locking lever 18 farther to the left, whereby the arm 15 on the lower end of this lever i l is swung out of the recess 12 as shown in dotted lines, thus permitting all the candies to drop vertically, in the corresponding chute, so that the lowest candy at rests upon the bottom of the casin Under the action of the turning disk 6 the coin slides to the lower end of the cam ed e 2% and then drops into the receptacle 11 thereby re leasing the lever 14-, and by the action oi the spring acting on the locking lever 18 the lever 1% is thrown at its upper end suddenly and forcibly to the right, that is, toward the vertical plane through the shaft l, and the lower end carrying the arm 15 is thrown suddenly and forcibly to the left and the outer edge ofthis arm encounters the inner end of the lowermost candy which now rests upon the bottom of the casing and the arm 15 passes into the recess 12 and thereby this lowermost candy is forced by said arm 15 through the slot 13 out of the receptacle. The left hand lever lei and its locking lever 18 then assume the position shown in full and dotted lines at the right hand side of Fig. 1. lhe parts are now locked and it is impossible to push the lower end of the lever is inward by means of an implement inserted through the slot 13,, Even if the notched disk 6 1s turned so that the recess 7 in the same is opposite the corner 36 of locking lever, thus per nut-ting said locking lever to be auce downward at the said point, it is impossible to operate the device by pushing the arm 15 by means of an implement inserted through the slot 13 because the toe 16 at the upper end of the lever ll is locked in the notch Or recess 1? of the locking lever, All the parts are of simple construction and can all be made out of stamped sheet metal.

El bracket it) may be secured to the bottom of the casing 1 so as to project beyond one side edge and this bracket is provided on its outer edge with an upwardly extending flange ll and upon this bracket the candy may be delivered. To facilitate removing the candy the bracket may have a notch 42. @n the top of the candies a a weight e3 rests which can move down as the candies are successively pushed out at the bottom of the stack. A cord ll is attached to this weight and passes over a grooved pulley on the underside of the top of the casing and is connected with a locking plate 46 pivoted at ii to the underside of the top of the box, which lever is connected at its free end by a spring l8 with a pin 49 on the underside of the top or the box, which spring hold one edge of said lever against the stop pin 50. As long as there is candy in any one chute the weight t3 cannot pull down on the cord ll and thus the spring 48 holds the locking plate all away from beneath the coin slots 27 as shown in Fig. 2, but when all the candies have been removed and the corresponding chute is empty the weight it; can now exert suliicient downward pull on the cord it to swing the plate 46 under the coin slots 2'? against the tension of the spring 48, thus serving to lock the coin slots 27 and preventing persons inserting coins as long as there is nosupply of candies or other articles in the corresponding chute.

Having described my invention what 1 claim as new and desire to secure by Letters Patent is 1. in a vending machine, the combination with a lever adapted to force out goods from a vending machine, of means adapted to re ceive a coin to operate said lever, and looking means for said lever adapted to lock the coin before the coin completely operates said lever.
